7th grade math

posted by .

There are 150 students in 7th grade. After signing up for electives for next year, the counselor posted the following data:

Art - 65 students
Band - 70 students
Theatre - 50 students

Not all students signed up for an elective.
Display this data using Venn Diagrams.

I do not think there is enough information to do anything but draw three intersecting circles.
Am I missing something?

    I don't believe the teacher's solution:
    30 take just art
    30 take just theater
    45 take just band
    15 take all three
    15 take none
    5 take art and band
    5 take art and theater
    5 take band and theater
    What do you think?
